KRACK Attack Devastates Wi-Fi Security

October 16, 2017 – 10:36 AM

A devastating weakness plagues the WPA2 protocol used to secure all modern Wi-Fi networks, and it can be abused to decrypt traffic from enterprise and consumer networks with varying degrees of difficulty.

Not only can attackers peek at supposedly encrypted traffic to steal credentials and payment card data, for example, but in some setups, a third party could also inject malicious code or manipulate data on the wireless network.

Some vendors have already issued security updates and users are advised to patch immediately. U.S. CERT has published a list of affected vendors, but users should note the list is not comprehensive.
